Why do dustbins have decibel ratings?

OK.  How about "username checks out"?

"Margaret...Margaret...tell the kids to come inside, next door's slamming the bins with progressively larger amounts of green waste inside them again!"

@politecameraaction I think that you have the impression that I’m an uncaring bin lid banger. I’m retired so can conduct my “research”  whilst others are at work, I’m usually the one who brings neighbour’s bins up as they somehow manage to negotiate their various vehicles past the entrance of our shared drive. I think I’m providing a useful insight, especially on the day before the election as dustbin collections are quite high up in people’s priorities along with potholes and 20mph limits. Apparently. @cougar I don’t understand the username bit!
